i am facing a problem regarding async storage in react native

i am facing a problem regarding async storage in react native .
when i setItem in async storage and then retrieve it if there are 3 tasks- which i have added,
only two of them is retrieved
i will share a photo of before and after
this is output before refreshing
this is the output after refreshing the app
This is my app.js code

Due to React internal state update implementation, update Async storage run before new state updated. It's recommended to run asynchronous code before updating the state.
To solve the issue, refactor your code as below:
handleAddTask= async ()=>{
Keyboard.dismiss()
const updatedTaskItems = [...this.state.taskItems,this.state.task]
await AsyncStorage.setItem('data',JSON.stringify(updatedTaskItem))
this.setState({taskItems:updatedTaskUtems,task:''})
}

I have added circular progress by using the react-native-progress library. I have implemented logic for moving bar for 30 sec but the thing is after 30 sec it stops, so I need to keep moving after 30 sec here my whole code.
Here is the logical part which I have added here...
constructor() {
super();
this.state = {
progress: 0,
indeterminate: true,
clipboardText: "",
textInputText: "",
};
}
componentDidMount() {
this.animate();
}
animate() {
let progress = 0;
this.setState({ progress });
setTimeout(() => {
this.setState({ indeterminate: false });
const interval = setInterval(() => {
progress += Math.random() / 30;
if (progress > 1) {
progress = 1;
clearInterval(interval);
}
this.setState({ progress });
}, 600);
}, 600);
}
I have tried several ways but nothing is happening also function will be welcome for this question. thanks in advance

create a curved bottom navigation (before after implementation)

How can I achieve this in react native?
So far I have this and I want to implement the middle curve. I don't know to either handle it with a transparent view or switch to SVG completely
and this the tabBar component
/* eslint-disable react/prop-types */
import React, { Component } from 'react'
import { TouchableOpacity, Text, StyleSheet, View } from 'react-native'
import { Colors } from 'App/Theme'
export default class TabBar extends Component {
render() {
let {
renderIcon,
getLabelText,
activeTintColor,
inactiveTintColor,
onTabPress,
onTabLongPress,
getAccessibilityLabel,
navigation,
showLabel,
} = this.props
let { routes, index: activeRouteIndex } = navigation.state
return (
<View style={styles.tabBar}>
{routes.map((route, routeIndex) => {
let isRouteActive = routeIndex === activeRouteIndex
let tintColor = isRouteActive ? activeTintColor : inactiveTintColor
return (
<TouchableOpacity
key={routeIndex}
style={styles.tab}
onPress={() => {
onTabPress({ route })
}}
onLongPress={() => {
onTabLongPress({ route })
}}
accessibilityLabel={getAccessibilityLabel({ route })}
>
{renderIcon({ route, focused: isRouteActive, tintColor })}
{showLabel ? <Text>{getLabelText({ route })}</Text> : null}
</TouchableOpacity>
)
})}
</View>
)
}
}

you need to use react-native-svg

i hope this will help you.

Here is 2 solution according to your requirement.
If you want this type of design without selection then this code will help you :
https://github.com/alex-melnyk/clipped-tabbar
And if you need on each tab selection then here is other easy library for you :
https://github.com/Jm-Zion/rn-wave-bottom-bar

It's not obvious that this can be done with only <View/> components. I would split the TabBar into a flex row container with three subviews, and create an SVG with the filled inverted radius to be used in the center subview. To render the SVG, use react-native-svg. See a rough layout below:
...
import { SvgXml } from 'react-native-svg';
import TabCenterSvg from ‘assets/my-svg.svg’
export default class TabBar extends Component {
render() {
return (
<View style={styles.tabBar}>
<View style={styles.leftContainer}>
{/* Left Buttons */}
</View>
<View style={styles.centerContainer}>
<View style={styles.centerInnerTopContainer}>
{/* Add Button */}
</View>
<View style={styles.centerInnerBottomContainer}>
<SvgXml xml={TabCenterSvg} />
</View>
</View>
<View style={styles.rightContainer}>
{/* Right Icons */}
</View>
</View>
)
}
}
const styles = StyleSheet.create({
tabBar: {
alignSelf: 'center',
borderRadius: 50,
bottom: 10,
elevation: 2,
flexDirection: 'row',
height: 65,
position: 'absolute',
width: '95%',
},
leftContainer: {
flex: 1,
flexDirection: 'row',
borderBottomLeftRadius: 50,
borderTopLeftRadius: 50,
borderTopRightRadius: 50,
backgroundColor: Colors.primary,
},
centerContainer: {
flex: 1,
flexDirection: 'column',
},
centerInnerTopContainer: {
flex: 1,
},
centerInnerBottomContainer: {
flex: 1,
},
rightContainer: {
flex: 1,
flexDirection: 'row',
borderTopLeftRadius: 50,
borderTopRightRadius: 50,
borderBottomRightRadius: 50,
backgroundColor: Colors.primary,
},
})

Use this library's code and customize according to your UI
https://www.npmjs.com/package/curved-bottom-navigation-bar
Note: I'll not recommend this library as there are low weekly downloads.
Rather than using the whole library, you can use its code.

React Native Maps - the Card View is not showing

How to slide <View/> in and out from the bottom in React Native?

In React Native iOS, I would like to slide in and out of a like in the following picture.
In the following example, when a button is pressed, the Payment Information view pops up from the bottom, and when the collapse button is pressed, it goes back down and disappears.
What would be the correct and proper way to go about doing so?
Thank you in advance!
EDIT

Basically, you need to absolute-position your view to the bottom of the screen. Then you translate its y value to equal its height. (The sub view must have a specific height in order to know how much to move it)
Code:
'use strict';
import React, {Component} from 'react';
import ReactNative from 'react-native';
const {
AppRegistry,
StyleSheet,
Text,
View,
TouchableHighlight,
Animated
} = ReactNative;
var isHidden = true;
class AppContainer extends Component {
constructor(props) {
super(props);
this.state = {
bounceValue: new Animated.Value(100), //This is the initial position of the subview
buttonText: "Show Subview"
};
}
_toggleSubview() {
this.setState({
buttonText: !isHidden ? "Show Subview" : "Hide Subview"
});
var toValue = 100;
if(isHidden) {
toValue = 0;
}
//This will animate the transalteY of the subview between 0 & 100 depending on its current state
//100 comes from the style below, which is the height of the subview.
Animated.spring(
this.state.bounceValue,
{
toValue: toValue,
velocity: 3,
tension: 2,
friction: 8,
}
).start();
isHidden = !isHidden;
}
render() {
return (
<View style={styles.container}>
<TouchableHighlight style={styles.button} onPress={()=> {this._toggleSubview()}}>
<Text style={styles.buttonText}>{this.state.buttonText}</Text>
</TouchableHighlight>
<Animated.View
style={[styles.subView,
{transform: [{translateY: this.state.bounceValue}]}]}
>
<Text>This is a sub view</Text>
</Animated.View>
</View>
);
}
}
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
marginTop: 66
},
button: {
padding: 8,
},
buttonText: {
fontSize: 17,
color: "#007AFF"
},
subView: {
position: "absolute",
bottom: 0,
left: 0,
right: 0,
backgroundColor: "#FFFFFF",
height: 100,
}
});
AppRegistry.registerComponent('AppContainer', () => AppContainer);

I know it is a little bit late, but thought it might be useful for someone. You should try out a component called rn-sliding-out-panel. It works awesomely. https://github.com/octopitus/rn-sliding-up-panel
<SlidingUpPanel
draggableRange={top: 1000, bottom: 0}
showBackdrop={true|false /*For making it modal-like*/}
ref={c => this._panel = c}
visible={ture|false /*If you want it to be visible on load*/}
></SlidingUpPanel>
And you can even open it from an external button:
<Button onPress={()=>{this._panel.transitionTo(1000)}} title='Expand'></Button>
You can install it via npm: sudo npm install rn-sliding-out-panel --save on your react-native root directory.
I hope it helps someone :D

I've created a reusable BottomSheet component that accepts any content.
This is how it looks like:
Here's the code (in TypeScript) of the BottomSheet component:
import * as React from 'react'
import {
Animated,
Easing,
Pressable,
StyleSheet,
useWindowDimensions,
View,
} from 'react-native'
const DEFAULT_HEIGHT = 300
function useAnimatedBottom(show: boolean, height: number = DEFAULT_HEIGHT) {
const animatedValue = React.useRef(new Animated.Value(0))
const bottom = animatedValue.current.interpolate({
inputRange: [0, 1],
outputRange: [-height, 0],
})
React.useEffect(() => {
if (show) {
Animated.timing(animatedValue.current, {
toValue: 1,
duration: 350,
// Accelerate then decelerate - https://cubic-bezier.com/#.28,0,.63,1
easing: Easing.bezier(0.28, 0, 0.63, 1),
useNativeDriver: false, // 'bottom' is not supported by native animated module
}).start()
} else {
Animated.timing(animatedValue.current, {
toValue: 0,
duration: 250,
// Accelerate - https://easings.net/#easeInCubic
easing: Easing.cubic,
useNativeDriver: false,
}).start()
}
}, [show])
return bottom
}
interface Props {
children: React.ReactNode
show: boolean
height?: number
onOuterClick?: () => void
}
export function BottomSheet({
children,
show,
height = DEFAULT_HEIGHT,
onOuterClick,
}: Props) {
const { height: screenHeight } = useWindowDimensions()
const bottom = useAnimatedBottom(show, height)
return (
<>
{/* Outer semitransparent overlay - remove it if you don't want it */}
{show && (
<Pressable
onPress={onOuterClick}
style={[styles.outerOverlay, { height: screenHeight }]}
>
<View />
</Pressable>
)}
<Animated.View style={[styles.bottomSheet, { height, bottom }]}>
{children}
</Animated.View>
</>
)
}
const styles = StyleSheet.create({
outerOverlay: {
position: 'absolute',
width: '100%',
zIndex: 1,
backgroundColor: 'black',
opacity: 0.3,
},
bottomSheet: {
position: 'absolute',
width: '100%',
zIndex: 1,
// Here you can set a common style for all bottom sheets, or nothing if you
// want different designs
backgroundColor: 'dodgerblue',
borderRadius: 16,
},
})
I put this code in a file named BottomSheet.tsx.
This is how you use the BottomSheet:
import * as React from 'react'
import {
Pressable,
SafeAreaView,
StatusBar,
StyleSheet,
Text,
View,
} from 'react-native'
import { BottomSheet } from './src/BottomSheet'
const App = () => {
const [showBottomSheet, setShowBottomSheet] = React.useState(false)
const hide = () => {
setShowBottomSheet(false)
}
return (
<SafeAreaView style={styles.safeAreaView}>
<StatusBar barStyle={'dark-content'} />
<View style={styles.container}>
<Pressable
onPress={() => {
setShowBottomSheet(true)
}}
style={styles.showButton}
>
<Text style={styles.buttonText}>Show bottom sheet</Text>
</Pressable>
</View>
<BottomSheet show={showBottomSheet} height={290} onOuterClick={hide}>
<View style={styles.bottomSheetContent}>
<Text style={styles.bottomSheetText}>Hey boys, hey girls!</Text>
<Pressable onPress={hide} style={styles.bottomSheetCloseButton}>
<Text style={styles.buttonText}>X Close</Text>
</Pressable>
</View>
</BottomSheet>
</SafeAreaView>
)
}
const styles = StyleSheet.create({
safeAreaView: {
flex: 1,
},
container: {
flex: 1,
},
showButton: {
marginTop: 48,
padding: 16,
backgroundColor: 'mediumspringgreen',
alignSelf: 'center',
borderRadius: 8,
},
buttonText: {
fontSize: 20,
},
bottomSheetContent: {
padding: 40,
alignItems: 'center',
},
bottomSheetText: {
fontSize: 24,
marginBottom: 80,
},
bottomSheetCloseButton: {
padding: 16,
backgroundColor: 'deeppink',
borderRadius: 8,
},
})
export default App
Notes:
I've put an outer semitransparent overlay, but you can get rid of it by deleting it.
I've chosen to close the modal when you click on the outer semitransparent overlay. This is done with the onOuterClick callback, which is optional - don't pass it if you don't want to do anything.
I've put some styling (blue background + border radius) that applies to all bottom sheets, but you can remove it if you want to have different styles.

After a quite long search I found very good library called react-native-swipe-down with MIT licence.
It will help you make a slider <View /> with no effort.
I Hope this library help you out.
import SwipeUpDown from 'react-native-swipe-up-down';
<SwipeUpDown
itemMini={<ItemMini />} // Pass props component when collapsed
itemFull={<ItemFull />} // Pass props component when show full
onShowMini={() => console.log('mini')}
onShowFull={() => console.log('full')}
onMoveDown={() => console.log('down')}
onMoveUp={() => console.log('up')}
disablePressToShow={false} // Press item mini to show full
style={{ backgroundColor: 'green' }} // style for swipe
/>

To achive above type of requirnment we can take help of some greate libraries
1 #gorhom/bottom-sheet
2 react-native-raw-bottom-sheet
But if we want to do with nativelly please find a code below, I'll try to justify the answer:)
For some animation effects I'll take reference from blow site
how-to-create-moving-animations-in-react-native
import React, { useState } from 'react'
import { SafeAreaView, View, ScrollView, Text, Dimensions, TouchableOpacity, Animated } from 'react-native'
const App = () => {
const { height, width } = Dimensions.get('window')
const SCREEN_HEIGHT = Math.round(height)
const SCREEN_WIDTH = Math.round(width)
// Animation
const startValue = new Animated.Value(Math.round(height + height * 0.3))
const endValue = Math.round(height - height * 0.3)
const duration = 1000
const _showBottomView = (key) => {
const toValue = key === 'HIDE' ? height : endValue
Animated.timing(startValue, {
toValue,
duration: duration,
useNativeDriver: true,
}).start()
}
return (
